Specification of Letters Patent.

MACHINE FOR TREATING- LIQUIDS.

Patented May 21, 1912.

To all whom it may concern:

Be it known that I, JOHN \V. DAVIES, of Reading, in the county of Middlesex and State of lVI-assachusetts, have invented certain new and useful Improvements in Machines for Treating Liquids, of which the following is a specification, reference being had to the accompanying drawings, forming gated particles or globules of fatty matter or other material, whichit is desired to 'emulsify, may be so treated by themachine that the said segregated particles or globules of fat' or other matter may be d1s rupted and theirconstituents distributed through the milk, liquid or pther material,

forming the carrying" medium, to form a homogeneous emulsion.

The inventiori-- consists in the eculiar means for disriiptingtlie fatty 'gloules or particles'and' ixingthesame with the carrying liquid;

The invention'falsoconsists in such other. novel features "of c'onstruction and combi nation of parts asshall hereinafter be more I.

describedand pointed gout in the.--

fully claims. y Figure 1 represents a vertical sectional view of the improved machine for treating liquids taken o'nline 1-.-1 Fig. 2. Fig. 2

represents a plan view of parts of the same. Fig. 3 represents a cross sectional view taken on line 33 Fig. 1.

.Similar numbers of reference designate corresponding parts throughout.

As shown in the drawings, in 1ts preferred form 5 indicatesan outer chamber mounted on a tubular standard 6 furnished at its lower portion with the base 7 containing the through the opening 13 1n the wall of sai tubular standard.

Removably engaged with the socket 10 secured in screw threaded sockets in tact in order to offer resistance to the pasof shaft member 9 is the shank 14: of the shaft 15 which latter is journale'd in the standard 6 and, at its upper end, is provided with. the plate 16 having the 'axially disposed depression or concavity 17. Secured to said plate 16, by a series ofbolts 18, .18, is the upper plate 19 having the axially disposed inverted depression or concavity 20 and a series of channels 21, 21. communicating with said concavity 20 and with the axially disposed liquid receiving chamber 22 at the upper surface of said plate 19.

Embracing the liquid treating mechanism, formed by the plates or mixing elements 16 and- 19, is the pan 23 having at its upper portion the exterior trough 24 furnished with the drain pipe 25; extending through the wall of chamber 5, and the lower portion of the pan 23 having the drain pipe 26. The meeting faces of the plates 16 and 19 are preferably flat and said faces are held in contact by bolts 18, 18 which extend through smooth bores in plate "1 9 and are late 16. In practice it is found thatfthe bolt s 1'8,

'18 should preferably be screwed down sufiiciently-to bring the meeting faces of plates 16 and 19 approximately in intimatecona c of liquid between. Said plates.

. ear 12 is operatedin'any ordinary manner to effect the rotation of .gear 11, its shaft member 9 and shaft 15, with the liquid treatingelements formed by the plates 16 and 19, at a high speed. Milk or other liquid or material containing fatty matter, enerally 'in segregated globules, is supplier? to the receiving chamber 22 and passes downward through the channels 21, 21 into the chamber, formed between the-faces of plates 16 and 19 by the depressions 17 and 20 and, under centrifugal action caused by the rotation of said plates, said liquid is driven outward, between the flat faces of said plates 16 and 19, in a thin film while the fatty matter is so flattened, by being forced between said plates, that the globules are distended until disruption occurs and the constituents thereof are so mixed with the thinner liquid, by reason of the circulation of said liquid between Ethe Plates 16 and that the fatty matter, is

throughout the? from between the plates 16 and 19 it enters the pan 23, the contents of which are further 'mixedby the continued centrifugal den-'- 1 livery of additional liquid,-and from said pan the greater portion of the liquid is preferably drawn off through the pipe 26. I

' find, however, that the centrifugal action of the liquid, delivered'froin' between the plates fll6 and 19 into the pan 23, is so considerable thatsaid liquid tends to -,creep up the wall-iofithe pan and,- to receive such 1 iq- 'idiilpriovi'de the upper edge of the pan 23 When it is desired to remove the-pan 2,3

' from -the chamber 5Ithefplates lfi anfl- 1Q with the shaft are'firs t-v-liftedout and the pan 23.m ay then be removed; -Injg eplacing, i sald plates 16 and-19 and their shat-(2915 is of course necessary that the shank 14 of shaft 15 be engaged'inthesocket 10 of shaft member 9.

It is of course obvious that the plates 16 and 19 maybe rotatably mounted and driven inany desiredmanner to. efi'ect' the centrif-.

'ugal action on the liquid supplied between sald Plates. v It is also evident th at the shape of said plates, particularly: as regards their meeting or compression faces, may be varied from that herein shown, and I place no limitation -on the material from which said y ith the annulartrough 2 from which the 1. liquid is-drained through the pipe 25. v

plates or mixing members 16 and 19 are to be manufactured. 1 Having thus described my invention I claim as new and desiret'o secure by'Letters Patent- 1. A machine for treating liquid of the nature described comprising a pair of rotatable members having their faces in annular contact, and devices for pressing said members together.

2. A machine for treating liquid of the I nature described comprising a pair of 'rotatable members having their faces in contact and having a chamber? embraced by said contacting. faces and bolts extending through one of said members and adjustably. secured in the other of said members,

bolts for securing said faces in contact,.

and means for receiving the liquid after it has passedbetween said members.
